How to identify make and model of old whirlpool tub?

We bought a house with a broken whirlpool tub. When we turn it on, we can hear the motor hum but no air comes out of the jets. The previous owners inherited the tub in the same condition and made no attempt to get it repaired.

The problem I have is, how can I identify who made this tub and what model it is? I think it dates from the 1990s, when the bathroom was supposedly remodeled. But the only clue I have as to its identity is that the drain switch says "Kohler." Looking at Kohler's Web site, though, I can't find a model that looks like this one (this is not a high-end product and I'm guessing it's a cheaper brand that happened to use Kohler hardware).

Is there any kind of Web site that has a database of old models, or is there some secret place in the guts of the tub (I haven't opened the access panel yet) that would contain this info?

This is a problem common to all whirlpool/air jet style tubs. The pumps become air locked due to the water evaporating from lack of use. All tubs need, and have, SOME means of priming the pump, this is most likely what the problem was, originally, for you. This time in particular you found it to be electrical in nature but for future reference, for you and all who have these style of tubs, I am putting this out there. Some where on the tub, usually along the top edge of the tub is a vent knob that controls the amount of air that the pump is allowed to mix with the water for the jets, usually by closing this valve all the way (tub needs to be full of water of course) and running the pump for a minute or 2, you should be able to get the pump pumping water again, if not you may need to do something else with your particular set-up to get it purged of air, the pumps in jacuzzi tubs are designed to pump water, not air, so if the motor is running but you get no jet action, your most likely air locked and need to prime pump/purge air.

Model lsr5132pq0. Why won't it agitate?

I have an older model (about 15 yrs old) that a similar problem. I turned it on its side thinking it was a broken drive belt. There was no belt because it was a direct drive. I removed the motor and found a white plastic coupling (285753A) that had its teeth broken off. I found the part at a local parts store for about $10.

When I push the button on my american standard jacuzzi tub I hear the hum of the motor but jets don't come on

In my case I took the motor out and used a screw driver to turn the impeller in the front of the pump and the fins inthe back. Put it back together and it worked. I then used 2 tablesoons of dishwashing detergent and 1/2 cup bleach and ran it for 20 minutes to clean and degrease the impellers

My Aqua Glass Whirlpool tub has stopped working. The motor comes makes a sound when I turn it on but the jets are not working

Your motor is shot. you need a new pump. If it comes on and you can hear a hum then it is bad. If you can get us a model number of the pump we can recommend a replacement model for you.

It won't run. I hear the humming but it won't turn. It fills up but won't wash.

you probably just have a broken belt. If it doesn't ever move the tub but you hear the motor running this is likely to be the problem.

Whirlpool Stylemaster 4217141 tub not moving wash/spin cycles

Sounds like the drive belt is broken or very loose. Take off the back and check the belt. If loose or missing, tighten or replace. This is usually done by loosening the motor support bolts and moving the motor until the belt is tight, then re-tighten the bolts. Replace belt in the same way.

Bathtub jets don't work

The first step is to determine if the pump is working or not. Is there an external switch on the wall next to the tub? Can you hear the pump humming underneath? CHeck your fuse box to see if a breaker has been tripped.

I know those sound easy, but its always best to check the simple things first.

If you don't hear the pump running and its not the breaker, it has now become a bit more difficult project but still something any competent home owner can fix.

YOu have to access the electrical plug on the tub. It is 110v outlet that is underneath the tub on the same end as the switch or opposite the drain.

You needs to access the tub through the wall from the other side and check out that electrical connection. Could just be the the GFI switch thrown. If not then it cold be a bad pump or broken impeller.

For help if that's the case just post again as it is a length process.

Aquglass jet tub will only humm no bubbles out of none of the jet

When a motor hums, it usually is the result of what is called "locked rotor." This can occur when the motor's brushes remain on one pair of the commutator contacts. The magnetic field does not shift to the next set of windings and the rotor is locked in place by the unchanging magnetic field.

If you have access to the motor, turn on the power briefly and place your hand gently on the side of the motor. Probably you will feel the vibration of the hum you are hearing, together with some heat. In locked-rotor condition, the motor draws high amperage and heats up quickly. Turn off the power.

If this is the condition, the motor is shot and needs to be replaced. You should copy down the information from the name plate (model and serial number, manufacturer, horsepower, amperage, etc.) and contact the manufacturer or a local appliance parts store about a replacement.

As you said that you recently bought the house, you may have a home-owners warranty which may cover the appliance.
